Quote from @Blake R.: I wanted to get involved in land investing and made a post about it during the summer and have continued to look at it until now.I was questioning if I should trust a land guru in my area so I asked about it and got some feedback.So then I have searched for land investing education programs and a name was at the top on google and I saw he had a lot of information out there.I did research on him and watched a lot of his videos and it all sounded good but I heard him talk about how he now owns over 1000 doors in multi family, so I started thinking about it.
